School Leadership, Faculty, & Staff
The collaborative efforts and intentions of the Board of Trustees, alumnae, parent, employee, and student communities promote the energy, excellence, and values of the school.
Westridge teachers and administrators care about the lives of our students, and through example, strive to invest a lifelong love of learning in every student. More than 65 percent of Westridge faculty members have advanced degrees and many are continuing their education at the graduate level. As leaders within their profession and their disciplines, many faculty members present seminars and workshops to educators at local, state, and national levels.
